Should I Cut Back That Tall New Cane on My Buck Rose?

A single, vigorous, thick cane shooting up from the base of your pink or yellow Buck rose is likely a basal break—new growth from the bud union, not a sucker. To confirm, gently dig around the base: if the cane originates above the swollen bud union (the knobby graft point), it’s part of your desired variety. If it emerges below the union, it’s a rootstock sucker (usually Dr. Huey) and should be removed.

Managing a Basal Break

Basal breaks are great—they renew the plant. Let it grow, but tip-prune it to match the height of the other canes, encouraging lateral branching and more flowers. If it’s a sucker, tear it off at the root (don’t cut, or it will regrow). Either way, your rose will benefit from the attention.
